Description
This wireless vacuum gauge precisely measures absolute pressure to ensure complete vacuuming of the refrigerant circuit in air conditioning, refrigeration, and heat pump systems.
The Si-RV4 allows you to work on any type of refrigerant-based system quickly and safely. It easily connects to the Si-RM350 and Si-RM450 manifolds and the Sauermann Pilot mobile app.
Compatible with A1 / A2L / A2 / A3 refrigerants
Compatible with certain B1 refrigerants; see the refrigerant list for details on compatible refrigerants. The device should not be used with ammonia-type refrigerants (NH3 / R717).
